TOILET BOWL Filed Nov. 18, 1931 2 Sheets-Sheet 2 Inventor Patented Jan. `177, 1933 UNITED STATES PATENT DFFICE JAMES H. BENNETT, 0F DETROIT, MICHIGAN, ASSIGNOR OF ONE-HALF T0 EDWARD DONOVAN, 0F DETROIT, MICHIGAN; MARY J. B. PENNOYER ADMINISTRATRIX 0F `SAII'D JAMES H. BENNETT, DECEASED TOILET BOWL Application led November 18, 1931. Serial No. 575,885.

This invention relates to new and useful improvements in toilet bowls, the primary object of the invention is to provide means for dispensing with all after and undesirable odors.

It is therefore a salient ,feature of the invention to provide a toilet bowl which will be highly sanitary, and which at the same time will be inexpensive to construct, will consist of comparatively few parts', and which will otherwise be free as regards appearance, cost, and difficulty of installation now attendant by such toilet bowls as are now in use and are equipped to serve the same general purpose.

Other objects and advantages ofthe invention will become apparent from a study of the following description taken in connection with the accompanying drawings wherein:

Figure 1 is a side elevational view of a toilet bowl.

Figures 2 and 3 are vertical transverse sectional views therethrough.

Figure 4 is a fragmentary horizontal sectional view` through that portion of the bowl equipped with a motor housing.

Figure 5 is a diagrammatic view illustrating a wiring system employed in accordance with the present invention.

Figure 6 is a top plan view of with the seat cover removed.

b Figure 7 is a rear elevational view of the Figure 8 is a fragmentary vertical sectional elevational view of a slightly modied form of the invention, and

Figure 9 is atop plan view of the bowl with the seat and cover therefor removed.

Referring more in detail to the drawings, it will be seen that the toilet bowl is designated generally by the reference character 10, the sewer pipe -connected therewith by the reference character 11 and the feed pipe for flushing the bowl by the reference character 12 the bowl It will be seen that the invention is employed with a conventional type of bowl, the structure of which is altered to the extent of providing in the rear wall of the bowl adjacent the base thereof, a transverse chamber 13 opened at its` relatively opposite ends.

The chamber 13 is connected with the atmosphere through the medium of a passage 14 and extending upwardly through the rear wall of the bowl to the top or rim of the bowl as clearly suggested in Figures 2 and 9. Passage 14 constitutes an entrance passage for the chamber 13 and a vertical outlet passage 15 is provided for the chamber and thepassage 15 extends downwardly tothe base of the bowl and is connected to the sewcrpipe 11 through the medium of a conduit pipe 16 within which is arranged a check valve 17 the purpose of which valve 17 is to eliminate the escape of gas when the fan 18 and the ectric motor 19 which drives the fan are 1 e.

From a study of Figure 4 it will be seen that the motor 19 and the fan 18 driven thereby are housed within the chamber 13 and suitable closure plates 2O are provided for the open ends of the chamber.

In that form of the invention shown in Figures 1 to 7 inclusive, it will be seen that 75 the toilet seat 21 in accordance with the present invention is provided with a circular chamber 22 which is in communication with the interior of the bowl 10 through the medium of a circular series of apertures 23 provided in the under face of the seat. The series of apertures 23 serve as inlets for the chamber 22,' and a single outlet 24 is provided for the chamber and is adapted to register with the upper end of the passage 14 when the seat is in a position of rest on the top or rim of the bowl as clearly suggested in Figure 2.

The seat -21 to ether with the cover 25 therefor is hin edly mounted as at 26, a spring hinge being preferably provided and which hinge serves to normally retain the yseat slightly out engagement with the top .Uli

A outlet pipe,

27 when the seat 21 has be. wardly about its end into the top or rim oi the boni li. the circuit to the motor 'i9 restY parent in :in operation of the motor. tact 2) is arranged in circuit h the motor I9 and e source of supply mrongh the Inedium et a Wire 30.

Thi.. it will be seen 'Inll Contact with he caused to rotate w' g ed by the arrows 'f impure nir will. c 2Q passing therefrom,y and. 'from the pas g ber 13 and through. en ;.et to the sewer pipe Il.

Thus it will be seen t" for drawing oil all tei that n sanitary co vicinity ci the to?, .et ,c

In the forni of the ure 8 it will be seen the the seat 21a with a circular chend ventional ty e of Wood, in or other sent may be emp eyed and scour tc the under face thereof is an annular member 3i previded with a chamber 3i., and on itsinner periphery the member 31 is provided with a series of relatively spaced apertures 33 constituting inlets for the chamber A single outlet chamber 34 for the chamber 32 is provided in the bottom of the member 3l and is adapted to register with the upper end of the passage 14a as also clearly suggested in. Figure 8.

Even though I have herein shown and described the preferred embodiments of the invention, it is to be understood that the same is susceptible of changes, modifications and improvements within the scope of the appended claim.

Having thus described my invention, what I claim as new is:

In combination with a toilet bowl and its said bowl having a transverse chamber therein opening out through the sides of the bowl, closure means for the ends of said chamber, a motor driven fan in said chamber, said bowl having a conduit therein connecting the chamber with the drain ipe, and said bowl havin a second conduit t erein connecting the c amber with the upper edge ofthe bowl, a seat for the bowl having an annular passage therein, and ports connect- Ving the and sai seat having connecting the annu a r end of the second conduit when the seat 1s resting on the bowl, and means foxclosing the circuit to the motor when the seat is oca second port therein cu ied. In testimony whereof I ax my signature.
